1 Claim.

- This invention relates to new and useful improvements in an adjustable sprinkler for lawns.

The invention has for an object the construction of a sprinkler which is characterized by an outer tube extending from the top of a hollow body connected with a supply of water, a spray directing nut mounted upon said outer tube for controlling spraying of water from an area around the tube and within the hollow body, and an inner tube extending coaxially through said outer tube and provided with a spray directing nut for controlling the spraying water which passes through said outer tube, and a headed stud mounted in the outer end of said inner tube for controlling spraying of water passing thru the inner tube.

Still further the invention proposes the provision of holding nuts for holding the adjustment of the sprinkler.

Another object of the invention resides in a novel way for supporting the outer tube and inner tubes in relative positions with respect to each other, and in a certain position with respect to said hollow body.

Still further the invention proposes the association of a foot bar arranged in a manner to assist in mounting the sprinkler upon a lawn.

For further comprehension of the invention, and of the objects and advantages thereof, reierence will be had to the following description and accompanying drawing, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 5 is a fragmentary enlarged vertical sectional view of an intermediate portion of Fig. 1.

Fig. 6 is a fragmentary enlarged detailed view of Fig. 2.

Fig. 7 is a sectional view taken on the line I I of Fig. 6.

The adjustable sprinkler for lawns, according to this invention, includes a pipe fitting I0 connected with a hose coupling I I adapted to attach a hose I2 to the pipe fitting. A ground engaging peg I3 is mounted in the bottom of the 55 tting IIJ. This peg has a flange portion I3a for resting on the top of the ground I4 and a spike portion I3b for engaging into the ground. A foot bar I5 is mounted on the side of the fitting I0 so that one may engage his foot thereupon to assist in forcing the ground peg into the ground. A vertical pipe I6 is mounted upon the top of the fitting I0. A hollow body I'I is mounted on the top of the pipe fitting and is provided with an open top end I8. The body I'I is composed of a cylindrical central portion I'Ib and end bushings I 'Ia and I'Ic which are press fitted on the central portion.

' An outer tube I9 extends through the said open top end I8 and is coaXially arranged thereto and is of a diameter slightly smaller than the said open top to form a passage between the tube and the said open top. This tube I9 is fiXedly mounted on the said hollow body I'I. More specifically, the tube I9 is xedly mounted on a bridging element 20 which has prongs 2 9a at its sides. 'I'his bridging element is disposed transversely within the body I1 and the prongs 2!a are jammed against the inner wall of the body II for xedly holding the bridging element in position. Near the bottom end the tube I9 is formed with several apertures ZI through which water may enter the tube.

A spray directing nut 22, is mounted on thel tube I9 for controlling the passage around the tube and within the open top end I8. This nut 22 is threadedly engaged upon the tube I9 so as to be adjustable upwards and downwards to adjustably control the discharge. The spray directing nut 22 has a flared end portion 22a, with the sides thereof curved so as to direct the spray outwards.

An inner tube 23 extends coaxially through the outer tube I9 and projects from the top end thereof and is of a diameter smaller than the inside diameter of the outer tube so as to provide a passage 24 between the inner tube and the outer tube. This tube 23 is mounted on a plug 25 engaged into the bottom end of the tube I9. The plug 25 has passages 25a for water to enter the bottom of the outer tube I9. A spray directing nut 26 is threadedly engaged on the upper end of the tube 23 and has flared sides 26'5L to direct the spray laterally. 'I'his nut 26 may be adjusted upwards and downwards to control the discharge.

A lock nut 2'I is threadedly engaged on the tube I9 and normally abuts the top end of the spray directing nut 22 for locking the nut in adjusted positions. Another lock nut 28 threadedly engages the tube 23 and abuts the top of VVthe open top end of the inner tube 23.V

side by which itis threadedly mounted in the top end of the inner tube 23.

A tubular bushing nut 32 threadedly engages' the stud 30 and is adapted to be screwed down against the top end of the inner tube 23 for locking the stud 3U in an adjusted extended position. It is possible to loosen the Ynut 32 and then adjust the stud 30 upwards or downwards to, obtain a desirable spray. Thenut 32- may then be turnedV down. into a locking position. The water which passes up along the Ygrooves 3|, passes through Vthe nut 30V.A This nut is in the form of a bushing having knurling on its outer face. Y Y A The operation ofthe device is as follows:

The sprinkler is mounted upon -a lawn as inl f dicated in Fig. l. VWater is supplied through the hose l2. This Water will pass into the pipe fitting Il), then up through the AVertical pipe I8 and discharge into the hollow body l1.' At the lower end, the body is provided with the pressed iitted bushing |`|a to which the upper end of the pipe I6 threadedly engages. Y

The water entering the hollow body will pass up around and between the open portions of the bridging element 20. Some of the water will continue up and discharge from the passage between the open end |'8 of the hollow body and the tube 19. This stream of water will be di-` lrected laterally by the spraying nut 22.

Some ofthe water `from the hollow body Il' l to size and 'quantity by adjusting the spraying nuts upwards and downwards, as previously described.

The device is also constructed to present a 50s r'st hollow pipe and having anV outer diameter third spray. This third spray is produced by the water which passes 'through the inner tube 23, passing up through the longitudinal grooves 3| and striking the flared portion of the head 30a of the stud to be directed outwards in a spray. This spray may be adjusted'asV to the direction and quantity by adjusting the stud 30.

While I have illustrated `and described the preferred embodiments of my invention, it is to be understood that I do not limitmyself to the precise construction herein disclosed and the right is reserved to all changes and modications corn- ,ing within the scope of the invention as'deflned inthe appended claim. Y Y Y j Having thus described my invention, what I claim'as new, and desire to secure by United States Letters Patent is:

y In a lawn sprinklingidevice, a vertically disposed hollow body, the wall of said body at the upper end Vthereof forming an upwardly directed nozzle, a bridge aiXed across the interior of said body intermediate the ends thereof, said bridge having openings therethrough, `a rst hollow pipe having its lower endV afxed to saidbridge, the upper end of said rst hollow pipe projecting above the upper end of said body, the outer di.

ameter of said first hollow pipe being substantially less than the inner diameter of said nozzle whereby to allow passage of water vtherebetween, a second hollow pipe concentric with the -.bridge, the upper end of said second hollow pipe extending substantially above the upper end of the first hollow pipe, each of said hollow pipes and the space therebetween communicating with' the portion of said hollow body below said bridge,

threads on the upper portions of each of saidl hollow pipes, delector members threaded to each of said hollow pipesA for selectively throttling the' openings surrounding said pipes, said second holn low pipe having inner threads inY the top thereof iand a bolt havingrgrooves in the lower portion `thereof threaded to the threads in the top of Vsaid second hollow pipe k"for selectively closing' said second hollow pipe. e
